Introduction: There are limited population cohort data on overall and cause-specific mortality in colonic diverticular disease.

Objective: To measure overall and cause-specific mortality in colonic diverticular disease, compared to matched reference individuals and siblings.

Methods: Population-based cohort study ("the ESPRESSO study") in Sweden. There were 97,850 cases with a medical diagnosis of diverticular disease (defined by international classification of disease codes) and colorectal histology identified in 1987-2017 from histopathology reports. The mortality risk between individuals with colonic diverticular disease and matched reference individuals ( n = 453/634) from the general population was determined. Cox regression models adjusted for comorbidity estimated hazard ratios (HRs) for all-cause mortality.
